You need to study the theory of evolution if you wish to try do disprove it. From your explanation about, it is apparent that you lack an understanding of what is involved in evolution.
Languages have evolved over time. We only need to see the change from Latin to French, Spanish and Italian to understand this. So the variety of languages is not due to angry gorillas, as you claimed, but due to the isolation of peoples who then, over time, develop new sounds. This is also an excellent analogy of the progress of evolution. A Latin speaker did not suddenly give birth to a Spanish speaking child, but rather the language changed gradually over time, generation after generation. The parents can always communicate with the children, but as the language changes, people adapt to new words or pronunciations.
Similarly, we can see that species did the same thing over vast amounts of time. They slowly changed, even though there was very little difference between parents and offspring. This is borne out by the fossil record, genetics, among other scientific fields.
